LANTERN.

Specification of Letters Patent.

Patented Dec. 2, 1919.-

Application filed June 21, 1919." Serial No. 305,784.

To all whom it may concern:

Be it known that I, JOSEPH N. KLEMA, a citizen of the United States,residing at Austin, in the county of Mower and State of Minnesota, haveinvented certain new and useful Improvements in Lanterns, of which thefollowing is a specification, reference be ing had to the accompanyingdrawings.

This invention relates to certain improvements in lanterns and hasrelation more particularly to a top or dome therefor; and it is anobject of the invention to provide a novel and improved top or domeincluding means whereby the upper end portion of the globe or chimney ofa lantern is effectually engaged in a manner to maintain said globe orchimney in applied position. 1

It is also an object of the invention to provide a novel improved'deviceof this general character wherein the dome or top has arranged therein ayieldingly supported ventilator serving as a holding means for the globeor chimney of the lantern, together with means whereby the ventilatormay be adjusted as desired.

. The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved lanternwhereby certain important advantages are attained and the device ren-'dered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that myinvention may be the better understood, 1 will nowproceed to describev the same with reference to the accompanyingdrawings, wherein:

Figure 1 is a fragmentary vertical sectional view illustrating a dome ortopfor a lantern constructed in accordance with an embodiment of 'myinvention, a globe or chimney being shown operatively engaged therewith.

Fig. 2 is a view partly in top plan and partly in horizontal sectionof'the structure as illustrated in Fig. 1. i

Fig. 3 is a view similar to Fig. 1 but illustrating a further embodimentof my invention, and I y Fig. 4 is a view in top plan of of the dome ortop.

As particularly disclosed in Figs. 1 and 2 of the accompanying drawings,improved dome or top comprises a cylindrical the body body portion 1having its lower or inner marginal portion defined by an outstandingskirt 2. The skirt 2 is adapted to be engaged in a conventional mannerwith the upper end portion of the frame F of any desired type.

The upper portion of the body 1 is intersected by the radially disposedfiat strip or bar 3 provided at substantially the axial center of thebody 1 with an opening 1 through'which is disposed an elongated shank orbolt 5. The bolt or shank extends axially of the body 1 and is providedat its lower end with a fixed head or enlargement 6.

Threaded upon the central portion of the shank or bolt 5 is a nut orstop 7 which en gages the inner or under face of the strip or bar 3whereby the bolt or shank 5 is held against upward movement.

8 denotes a disk substantially snugly iitting within the lower portionof the boil. 1 and having its marginal portion defined by the'downwardlydirected flange 9. The central portion of the disk 8 is provided with anopening 10 through which the bolt or shank 5 is loosely directed so thatthe disk 8 is capable of movement longitudinally of said bolt or shank5.

The disk 8 is'also provided with an an. nular series of openings 12partially closed by the upwardly inclined plates or Wings 14 struck fromthe disk 8 and whereby the openings 12 are produced.

Overlying the upper or outer end of the body 1 is a cap 15 hereindisclosed as concavo convex inform and the central portion of said cap15 is provided with an opening 16 through which the upper or outer endportion of the bolt or shank 5 is loosely directed. Threaded upon theupper or outer end portion of the bolt or shank 5 is the nut or stop 17contacting with the outer face of the cap 15. Interposed between the cap15 and the member or bar 3 is an eXpansible member 18 herein disclosedas a coiled spring encircling the bolt or shank 5. The member 18constantly urges the cap 15 toward the nut or stop 17 and by movingsaidnut orstop 17 longitudinally of the bolt or shank 5, the cap 15 may beadjusted toward or from the body 1 as the occasions of practice mayrequire.

The wall of the body 1 is provided with the openings 19 through whichthe products of combustion may escape and which prodgagement of theglobe or chimney therewith.

The member 18 also operates to maintain the member or bar 3 in desiredposition be cause should said member or bar 3 expand under the influenceof excessive heat, the member 18 will serve to return the member or bar3 to normal position as it cools.

In the embodiment of my invention as illustrated in Figs. 3 and t thebody 1 has its upper marginal portion defined by an inwardly directedflange 20 provided at substantially diametrically opposed points by therecesses or notches 21.

Substantially midway of its length the body l is intersected by the flatmember or bar 3 having disposed through the central portion thereof theelongated bolt or shank 5 The bolt or shank 5 is held'in desiredposition by the member or bar 3 through the instrumentality 0f theclamping nuts 22 threaded upon the bolt or shank 5 and engaging theopposite faces of the member or bar 3 By proper adjustment of the nuts22, the bolt or shank 5 may be adjusted longitudinally as thenecessities of practice ma require.

The cap 15 at substantially diametrically opposed points and adjacentits periphery is provided with the depending or inwardly directed arms23 terminating in the outwardly directed lugs or feet 24 adapted tocontact with the inner face of the flange 20. In applying the cap 15" inposition the lugs or feet 24 are first passed through there cesses ornotches2l and said cap 15 is then partially rotated.

The lugs or feet 24: are maintained incontact with the flange 20 throughthe instrumentality of an expansible member 18 in terposed between thecap 15 and the upper or outer nut 22. As herein disclosed the member 18comprisesa coiled spring conoidal in form with its smaller enddownwardlyor inwardly directed.

The disk 8 is substantially the same con struction as hereinbefore setforth relative to the disk 8 and operates in the same manner and for thesame purpose as said disk 8 under the influence of the expans'iblemember 11 interposed between said disk S fand the member or bar3F. i 1

From the foregoing description, it is thought to be obvious that alantern constructed in accordance with my invention is particularly welladapted for use by reasonof the convenience and facility with which itmay be assembled and operated and it will 7 eral parts herein shown incarrying out my invention in claimed.
